Check Digit Verification of cas no

The CAS Registry Mumber 537049-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,7,0,4 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 537049-07:
(8*5)+(7*3)+(6*7)+(5*0)+(4*4)+(3*9)+(2*0)+(1*7)=153
153 % 10 = 3
So 537049-07-3 is a valid CAS Registry Number.

Synthesis of novel rigid triazine-based calix[6]arenes

Yang, Xiaoping,Lowe, Christopher R.

, p. 1359 - 1362 (2007/10/03)

In this report, the stepwise synthesis of a novel rigid and functionalised macrocycle 2 based on triazine and phenylenediamine linkers, is presented. Poor recognition of the macrocycle 2 for its substrates is observed, which shows experimentally that for the meltriazine based-calix[6]arene system, the binding ability of the melamine moiety gets more benefit from the ring flexibility derived from a xylenediamine linker 1 than from a phenylenediamine linker 2.
